. SPECIFICATION forming part of Letters Patent No. 562,109, dated June16, 1896.

Application filed October 21, 1895. Serial No` 566,287. (N model.)

parts hereinafter described, and particularly pointed out in the claims.The machine made the subject hereof embraces the usual parallelhorizontal feed-disks,

horizontal reciprocating needle and oscillating looper, all of which inthe present machine have theircustomary and usual movements.

The present invention resides in certain improvements in the mainsupporting-frame of the machine and in the operative mechanism-intermediate the feed-disks, needle and looper, and the maindriving-shaft.

The object of the invention is to simplify the operative mechanisms,reduce them in number, bring them into more effective operativerelations, render them more positive in action and more durable in use,and adapt them for convenient adjustment, and to produce a machinecapable of ready manufacture and ease of operation.

The invention will be readily understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which- Y Figure 1 is a vertical longitudinal section through amachine constructed in accordance with and embodying the invention, thesection being on the dotted line l l of Fig 3. Fig. 2 is a verticaltransverse section of a portion of saine on the ydotted line 2 2 of Fig.3 and illustrates a part of the front of the machine, a portion of thelatter being in section in line with the screw by which the feedmechanism may be adj Listed. Fig. 3 is a top View, partly in section, ofsame, the covering-cap for the frame of the machine being omitted. Fig.4 is a detached top View of a reciprocating bar which carries thelooper-bar. Fig. 5 is a detached vertical section of a portion of theniachine on the dotted line 5 5 of Fig. 3. Fig. (5 is a detachedelevation of one of the cams forming a part of the operative mechanismof the machine. Fig. 'Z is a transverse horizontal section of themachine on the dotted line 7 7 of Fig. l. Fig. S is a perspective viewof the cam shown in side elevation in Fig. (i. Fig. 9 is a verticalsection of same on the dotted line9l 9 of Fig. 6. Fig. 10 is aperspective View of a portion of the interior mechanism ofthe machineand is hereinafter specifically referred to, and Fig.11 is a perspectiveview of an actuating-arm which in use is intermediate the camillustrated in Fig. 8 and the looper bar and imparts motion from theformer to the latter.

In the drawings, A designates the main framelof the machine; B O, theusual horizontal substantially parallel feed-disks; D, the needle, and Ethe looper. The disks are of the usual well-known form and construction,the disk B being mounted upon the upper end of the usual revolublevertical shaft F, upon whose lower end the feed-actuating mechanism isapplied, as hereinafter described. The feed-disk O is mounted upon thelower inwardly-turned end G of the reciprocating bar l-I, the main bodyof which ascends above the disk C and thence turns directly rearwardthrough guides' l, formed in the frame A of the machine. The bar H isheld within the guides Iby means of the screws J J, entering the frameof the 1nachine,as illustrated in Fig. 3, and having their headsprojectin g over the upper surface of said bar H. In the base of theguide I is provided the screw K, upon which the bar H rests and theposition of which regulates the position of the bar H and consequentlythe relation of the disk O to the disk B. By adjusting the screw Kupward or downward the disk O may be adjusted vertically in accordancewith the character of the goods under treatment and the desire of theoperative. Upon the cap L of the frame A being removed the screws Jbecome exposed and upon their 'withdrawal the bar H may be removed andthe screw K adjusted at will. The screws J are adapted to the variouspossible adjustments of the bar H and will be screwed downward more orless in accordance with the position of the IOO being depressed by thefoot of the operative; the lower end of the lever N will be thrownrearward and this will have the effect of causp ing the upper end of theleverN to move the bar H and feed-disk C forward, thus separating thedisks B C and `permitting the insertion of the goods between them. Uponthe foot of the operative bein g removed from the usual treadle thespring P will restore the lever N to its normal position, thereby caus-`ing the bar Il and disk C to returnA rearward to their former position,the disk C pressing the goods against the edge of the disk B, as usual.

The upper end of the lever N is slotted, as

illustrated in Fig. l, and passes upon the pin Q, secured to the bar Il,and hence the lever N is enabled to actuate the bar Hin the manner abovedescribed. The spring P at its rear end is connected with the lever N,while at its front end said spring is connected with the screw R, whichpasses through the front of the machine and is provided with theadjusting-nut S. The screw R is not permitted to revolve, but is adaptedto have a direct longitudinal movement under the action of the nut S,the purpose of which is to enable the operative to conveniently regulatethe tension of the spring P upon the lever N, bar II, and disk C.

l t will be observed that the nut S is in convenient position to bereadily grasped by the operative and that the tension on the disk C maybe quickly and conveniently adjusted. The opposite sides of the screw Rare flattened, as indicated in Fig. '7, in order to prevent thc screwfrom revolving axially within the aperture through which it passes, the

walls of the aperture closely iitting against` the Iiattened sides ofthe screw.

The bar H4 is oi a form, as illustrated in Figs. 1 and 3, which leavesthe lower part of the machine entirely open for the reception of thegoods to be introduced between the feed-disks B C, and this is a featureof great importance, particularly when heavy seal goods are to betreated.

The needle-bar is lettered T and moves in guides formed in the frame ofthe machine. Upon the front end of the bar T is provided a usual head Vfor clamping the needle D, and within the frame of the machine there issecured upon the bar T the bifurcated frame lV, whose opposite memberspass downward upon the opposite sides of the grooved cam X, rigidlymounted upon the driving-shaft Y. The needle-bar T, frame NV, and cam Xare not in themselves new, and are shown in "Letters Patent No. 275,506,granted to W'. Ludeke April l0, 1888. The needle-bar T is given a duereciprocating movement through the frame Ytand cam X from thedriving-shaft Y.

The looper-rod proper is lettered c, and lit carries the usual looper Eand imparts to it a longitudinal reciprocating motion, a transverseoscillatory motion, and an up-and-down motion, all of which motions arecustomary and usual in this class of machines. The looper-bar a ismounted in the sleeves l; l) of the bar c, (shown in detail in Fig. 4,)which is at its rear end pivotally connected with the rod d by means Vofa screw e entering the sleeve j', the latter being integral with thesaid bar c. The bar d is mounted in guidingapertures in the frame of themachine and has a due longitudinal reciprocating motion therein, andupon the said bar Z is mounted a frame g, (shown in detail in Fig. 10,)the upper end of which forms a yoke h, encom passing the `grooved camt', secured upon the drivingshaft Y.

The action oi' the cam t' during the operation of the machine is toimpart to the rod d a reciprocating motion, the said cam coming intocontact with the opposite sides of the yoke h. One member of the frame gforms a down'wardly-extending rod j, carrying the cam m, which, duringthe reciprocating mo* tion of the frame g and rod d, serves to actuatethe feed mechanism, as hereinbeiore dcscribed. The cam 'L' and frame g,acting through the rod d, impart to the frame c a rcciprocating motion,and since said frame c carries the looper-bar a the latter will, duringthe operation of the machine, have imparted to it a reciprocatingmotion. lt is necessary, however, that, in addition tothe reciprocatingmotion, the bar a shall have an axial motion and an up-and-down motion,and hence the bar c is actuated from the cam m through the arm o to haveits upanddown motion, and the bar a is actuated from the cam j) throughthe curved arm q to have its axial motion, the latter being essential tocause the looper to have an oscillatory motion across the path of theneedle. The arm q is illustrated in Fig. ll and has upon one end thesleeve Ir, which is secured upon the bar a, while at the other end ofsaid arm q is provided the roller s, which enters the cam-groove p, asillustrated in Figs. 2 and S. During the revolution of the driving-shaftY the cam p 'will cause the lower end of the arm (l to have anoscillating movement, and since said arm is secured by a screw or othermeans to the bar a the latter will have imparted to it au axial movementwithin the sleeves l) b, conneeted with the bar c. The revolving motionof the driving-shaft Y, acting through the cam n and arm o, will, duringthe operation ol' the machine, cause the barc to have an 11p-anch downmovement, and since the bar c is coI1- lOl) IIO

nected with the bar a the latter and the looper E will have 'imparted tothem the proper upand-down motion. In view of the fact that the bar'c ispivotally connected with the rod d the said bar may have the up-and-downmotion just referred to without interfering with its reciprocatingmotion. The cams a p are formed in the wheel t, which is eccentricallysecured upon the driving-shaft Y.

Upon the lower end of the vertical feedshaft F is rigidly secured,within the frame of the machine, the disk w, which has anupwardly-extending annular rim which supports the two pawls A', thelatter at their outer ends being thickened and grooved to fit upon theupper edges of said rim cc, as indicated more clearly in Figs. l and 7.The shaft F has mounted upon its lower end, above the disk w, the armB',which extends rearwardly, and is provided with a stud C' and spring`D', the stud being in Contact with the cam m, here'inbefore referred to,and being caused to follow' the outline of said cam by means of thespringD'.

The arm B carries the pins E', to which are'y connected the'springs F',which pass thence to the pawlsV A', as indicated in Fig. 7, and uponsaid armB', adjacent to the base of the shaft F, are provided theratchet-teeth G', which are engaged by the points of the pawls A'.During the reciprocating motion of the rod d and frame `g the cam m,carried by said frame, moves against the stud C' on the arm B' andcauses the latter to have an oscillatory motion, whereby theratchet-teeth G' are caused to act upon the pawls A and through saidpawls to rotate by intermittent motions the disk w and shaft F.k'lhedisk tu, having the rim @the pawls A', and ratchet-teeth G',engaging said pawls, are not of themselves new at this time, they havingbeen shown and described in the aforesaid Letters Patent of the UnitedStates, No. 275,506.

The front end of the arm B' extends forward of the shaft F and operatesin connection with the stop H' to limit the movement of the arm B' anddisk w. The stop H' consists of the threaded rod mounted in a threadedaperture formed .in the frame of themachine, as illustrated more clearlyin Fig. 7,

and said stop II' is provided with a head I',

by which it may be adjusted to suit prevailing conditions. B y movingthe stop H' outward the bar B' is permitted to have a larger throw, andconsequently the disk w will under each movement of the cam m have amore extended axial motion, and when the stop H' is adjusted inward. theextent of movement of the arm B' is restricted and the disk Iw will havea shorter intermittent revolving motion. The arm B', as shown in Fig. 7is moved in one direction by the cani 'm and in the opposite directionby the spring D'. lVithin the machine I have provided the guide-rod J'for the frame g, and upon the end of this rod J' is formed the flangeK', which Serves as a stop at the end of the natural movement of theframe g. The guide-rod J' serves not only to guide the frame g, but tobrace the lower portion of same and keep the cam m with firmness againstthe stud C' on the arm B'. In the absence of the rod J' the force of thespring D' might tend to prevent regularity of action in the cam Fm.

The frame A may be of any suitable or usual construction, but in thepresent instance I have provided certain advantageous features intheframe A shown. Great difficulty has been experienced in preventing theoil used in the machine from getting upon the fur garments beingtreated, and to overcome this objection the bar I-I has been carriedupward and rearward out of the way and the bottoni of the frame A hasbeen closed, as indicated by the solid bottom L' in Fig. l.

The rear portion of the frame A is provided with a door M', by which theinterior mechanism, with the exception of the feed mechanism, may bereached, and in order that the feed devices may be readily inspected theupper front portion of the frame A isprovided with the covering-plate orhorizontal door N', the latter being directly over the feed-disk w andbeing secured in a hinged manner by means of the lugs O', engaging pinsP', the latter being upon the frame of the machine and the former uponthe lid or door N'. The central portion of the cover N' is cut away toiit around the bracket Q' for the lower end of the shaft F, and the lugsO' are at the outer corners of the said lid or cover and pass upon theopposite side edges of the machine,as illustrated :more clearly in Fig.7.

It will be noticed that upon the elevation of the lid or cover N' thepawls A', springs F', disk w, and stop II' are all exposed and may bereadily reached. The presence of the cover N' in the position referredto possesses the further advantage that the machine does not have to beturned upside down, as heretofore, when the operative desires to get atthe feed mechanism.

In the arrangement of the parts of the machine an aperture is formed inthe bottom L' of the machine, and the screw securing the disk w to theshaft F is inserted upward through this aperture, which is thereafterclosed by the screw-'plug W', as illustrated in Fig. l.

As above described, the motions imparted to the needle, looper, andfeed-disks'are the usual and customary motions for this class ofmachines.

The machine constructed in accordance with the present invention 'is ofgreat simplicity, durability, and efficiency and has an ease andsmoothness of movement and posi- IOO IIO

tiveness of action not before attained, sofar ted from the maindriving-shaft Y through the medium of the cam i, frame g, cam Vm, armB', disk yw, and pawls A'. The needleD has aplain rccip rocating motion,as usual, andreceives the same from the `main driving-shaft Y throughthe cam X, frame IV, andneedlebar T. The looper E receives itslongitudinal reciprocating motion from the main drivingeshaft Y throughthe `cam i, frame r, bar c, and looper-rod a, and said looper hasimparted to it its usual up-and-down motions or its motion from theposition shown in Ifig.' l upward from the disk B, then downward whenover the 'disk C, then upward when over and about to leave said disk C,and then down.

ward "when over the diskB to the pesition shown in Fig. l, through theinstrumentality of the cam n, arm 0, frame c, and looper-rod a, thelatter and the armc at `such time having a longitudinal oscillating orrecking motion on the screw c. The loo'per E receives its usnaloscillatory motion across the path of the needle D by 'means of the camp, `arm q, and 4ro'd a.
